Abstract

The output-feedback event-triggered (Formula presented.) controller is designed in this paper for singular active seat suspension systems. The human body is simply separated into two parts (body torso and head) and is considered with the seat suspension system. The accelerations of each part are considered as part of the system states, which makes the system as a singular system. The seat suspension deflection, relative velocity, the accelerations of the seat frame, body torso, and head are defined as the system outputs, which are all measurable in real-time. The output-feedback (Formula presented.) controller is designed at first. Then, the event-triggered scheme is designed for the seat suspension system to reduce data transmission. Linear matrix equalities criteria are presented to get the controller and event-triggered scheme and ensure the admissibility of the seat suspension system. Simulation results are shown to illustrate the effectiveness of the considered control method.
